This invention relates to thev class of household and like forms of refrigerators having chambered walls, the chambers of which receive the cold drip water from the melting ice used as the refrigerating medium, to resist the passage of exterior heat to the interior of the refrigerator and in consequence maintain .said interior at the desired low degree of temperature in an efficient and economical manner. And the present improvement has for its various objectszf To provide a structural formation and combination of parts in an inner lining or wall for the storage chamber of a refrigerator of the type described, whereby an initial inner downward flow of the cold drip water, and a succeedin outer upward flow of the same is attaine with such iiows insulated against heat exchange.

To provide in connection with the subchamber for such u ward How of the drip water, a vertical drain duct adapted rto carry od the surplus and comparatively warm upper strata of water in such sub-chamber.

To provide an interengaging sectional formation of the inner lining or walls of a Arefrigerator of the type described, adapting the same for ready assemblage, disassembl and removal for repair and replacement, a as will hereinafter more fully appear.

Like'reference numerals in icate like parts in the several views.

In the drawin the ,invention is shown applied to the or 'nary rectangular form of household refrigerator, having rear and side walls 1 and 2 and hinged doors 3 at front, to constitute the outer housing of the article, with the interior of such housing divided by a horizontal orificed partition 4 into a lower storage chamber 5 for food and the like, and

an upper chamber for the reception of a cake of ice used as the cooling medium in the refrigerator. Such construction is 01d and in general use and may vary in detail construction and association of the parts as the judgment of the constructor,or particular applications, may direct.

In. connection with arefrigerator construction substantially as above described, the present invention comprises a hollow and preferabl sectional lining or su plementary lnner wa l for the storage cham er 5 of the refrigerator, constructed as follows A plurality of hollow casings 7, 7 of a flat rectangular shape and of a size complementary to the rear and side faces of the aforesaid storage chamber 5 are formed with o'set tongues or flanges 8 at their meeting edges to form interengaging means between the casings when the same are assembled in operative relation, and in the present improvement each casing 7 and 7 is divided by" a vertical partition 9 of a heat insulating construction as shown, into ay pairof sub-chambers 10 and l1 connected together at their lower ends by a transverseconnecting passage 12 with the upper end of the outer sub-chamber 11 having a closed formation while the u per end of the companion and inner sub-c amber. l0 is of an open formation adapted to receive the cold drip water as it comes from the melting body of ice in the upper compartment 6 of the refrigerator. To such end the top wall or roof 13 of the storage chamber 5 has a hip form as shown in order to shed the drip Water into the sub-chambers 10 of the plu rality of casings 7.

With the above described construction and arrangement of parts, the cold drip water fills the two sub-chambers 10, 11, and has a gradual ow down throu h the sub-,chamber 10 and up through the su -chamber 11 to attain an eective and very economical cooling action on the interior of the storage charnber 5v of the refrigerator, in that the colder drip water in its downward passage in the sub-chamber 10, is next to said storage chainber 5, While the drip water, in a less cold condition, due to absorption of heat, in its' upward passage in the sub-chamber 11, acts to prevent inward transmission of heat from the exterior of the refrigerator to the body of cold water passing down through the inner'sub-chamber 10.

In actual construction, the excess or spent with a suitable drain panor drain pipe of the building.

With the use of a single outlet pipe 14 as 15 above set forth, the upper ends of the subchambers 11 in the side casings 7 will have communication with vthe upper end of the" sub-chamber 11 in the rear casing 7 f by lateral overflow pipes 16 which extend through 20 adjacent orifices in the walls of the subchamber 11 of section 7', to discharge intothe same.

Havin thus fully described my invention, what I c aim and desire to secure by Letters Patent, is

1, The combination with the enclosing housing of a refrigerator and the upper ice containing compartment and lower storage compartment of the same, a casing in the Stora e compartment having a central closed cham er partially surrounded b hollow walls, an insulated partition in said hollow walls dividing the same into inner and outer sub-chambers, with said sub-chambers communicating one with the other. at their lower ends, with the upper end of the inner subchamber in communication with theice containing compartment aforesaid and with the upper end, of the outer sub-chamber having off the surplus water from the upper end of said outer sub-chamber.

2. The combination with the enclosing housing of a refrigerator and the upper ice containing com artment and lower storage compartment o the same, of an inner lining for said storage compartment formed by a flat casing having a vertical partition of anA insulating nature dividing the ^casin into inner and outer sub-chambers, with said subchambers vcominunicatinglf one with the other at theiry lower ends, with the upper end of the inner sub-chamber in communication with the ice containing compartment afore- 5'* said and with the upper end of the outer sub-'chamber having a closed formation, and' 6 containing compartment andy lower storage a closed formation, and means for drawing.
